Dogs wag(摇摆) their tails in different directions depending on whether they are excited and wanting to move forward or threatened and thinking of moving back, a study has found.
Researchers in Italy examined the tail wagging behaviour of 30 dogs, catching their responses to a range of stimuli(刺激物) with video cameras. To conduct the study they chose 15 male dogs and 15 female ones aged between one and six years. The dogs were all family pets whose owners had allowed them to take part in the experiment at Bari University. The dogs were placed in a large wooden box with an opening at the front to allow for them to view various stimuli. They were tested one at a time.
The researchers led by Professor Giorgio Vallortigara of the University of Trieste found that when the dogs were shown their owners—a positive experience—their tails wagged energetically to the right side. When they were shown an unfamiliar human they wagged to the right, but with somewhat less enthusiasm. The appearance of a cat again caused a right-hand side wag, although with less intensity again. The appearance of a large unfamiliar dog, similar to a German shepherd, changed the direction of tail wagging to the left. Researchers supposed the dog was thinking of moving back. When the dogs were not shown any stimuli they tended to wag their tails to the left, suggesting they preferred company. While the changes in the tail wagging were not easily noticed without the aid of video, it was thought that the findings could help people judge the mood (心情) of dogs. Computer and video systems, for example, could be used by professional dog trainers to determine the mood of dogs that they were required to approach.The video cameras were used to catch the dogs ’responses because .

The Eiffel Tower was built in 1889, in memory of the 100th birthday of the French Revolution. The Prince of Wales, later King Edward VII of England, opened the tower. Of the 700 suggestions that were handed in, Gustave Eiffel’s was chosen.
However, at first, it was not well accepted by all and a group of people — including many well-known writers and painters at that time — were fiercely against its design.
Being about 300 meters in height, and 7,000 tons in weight, it was the world’s tallest building until 1930. It was a great project for France. 300 workers took two years to build it. It isn’t an ordinary building, since it is almost made of steel. For example, its body moves around at most 12 cm in heavy wind. Moreover, its height changes up to 15 cm according to the temperature.
It was almost destroyed in 1909, but was saved because of its antenna(天线), which is used for communication at that time. Beginning in 1910 it became part of the International Time Service. French radio and French television have also made good use of its height.
The Eiffel Tower has also seen a few strange things. In 1923, a journalist rode a bicycle down from the first level of it. And in 1954, a mountain climber climbed on top of it and tried to measure its exact height.
Anyway, although its birth was difficult, it is now well accepted all over the world. It has been considered as one of the symbols of Paris. The passage mainly tells us ________.
| A．the history of the Eiffel Tower |
| B．some information about its design |
| C．what the Eiffel Tower was used for |
| D．how it became one of the symbols of Paris |
Which of the following statements is TRUE according to this passage?
| A．Many people couldn’t accept the Eiffel Tower at the beginning. |
| B．It was the world’s tallest building for hundreds of years. |
| C．A journalist rode down from the Eiffel Tower in 1954. |
| D．The Eiffel Tower was saved because of its height. |
The French Revolution took place in _______.
| A．1889 | B．1923 | C．1789 | D．1930 |
When students and parents are asked to rate subjects according to their importance, the arts are unavoidably at the bottom of the list. Music is nice, people seem to say, but not important. Too often it is viewed as mere entertainment, but certainly not an education priority(优先). This view is shortsighted. In fact, music education is beneficial and important for all students.
Music tells us who we are because music is an expression of the beings who create it, it reflects their thinking and values as well as the social environment it comes from. Rock music represents a lifestyle just as surely as does a Schubert song. The jazz influence that George Gershwin and other musicians introduced into their music is obviously American because it came from American musical traditions. Music expresses our character and values. It gives us identity as a society.
Music provides a kind of perception (感知) that cannot be acquired any other way. Science can explain how the sun rises and sets. The arts explore the emotive (情感的) meaning of the same phenomenon. We need every possible way to discover and respond to our world for one simple but powerful reason: No one way can get it all.
The arts are forms of thought as powerful in what they communicate as mathematical and scientific symbols. They are ways we human beings “talk” to each other .They are the language of civilization through which we express our fears, our curiosities, our hungers, our discoveries, our hopes. The arts are ways we give form to our ideas and imagination so that they can be shared with others. When we do not give children access to an important way of expressing themselves such as music, we take away from them the meanings that music expresses.
Science and technology do not tell us what it means to be human. The arts do. Music is an important way we express human suffering, celebrations, the meaning and value of peace and love.
So music education is far more necessary than people seem to realize.According to paragraph 1, students.
| A．regard music as a way of entertainment |
| B．disagree with their parents on education |
| C．view music as an overlooked subject |
| D．prefer the arts to science |
In Paragraph 2, the author uses jazz an example to.
| A．compare it with rock music |
| B．show music identifies a society |
| C．introduce American musical traditions |
| D．prove music influences people’s lifestyles |
According to the passage, the arts and science.
| A．approach the world from different angles |
| B．explore different phenomena of the world |
| C．express people’s feeling in different ways |
| D．explain what it means to be human differently |
What is the main idea of the passage?
| A．Music education deserves more attention. |
| B．Music should be of top education priority. |
| C．Music is an effective communication tool. |
| D．Music education makes students more imaginative. |

I am a writer. I spend a great deal of my time thinking about the power of language — the way it can evoke(唤起) an emotion, a visual image, a complex idea, or a simple truth. Language is the tool of my trade. And I use them all — all the Englishes I grew up with.
Born into a Chinese family that had recently arrived in California, I’ve been giving more thought to the kind of English my mother speaks. Like others, I have described it to people as “broken” English. But I feel embarrassed to say that. It has always bothered me that I can think of no way to describe it other than “broken”, as if it were damaged and needed to be fixed, as if it lacked a certain wholeness. I’ve heard other terms used, “limited English,” for example. But they seem just as bad, as if everything is limited, including people’s perceptions (认识) of the limited English speaker.
I know this for a fact, because when I was growing up, my mother’s “limited” English limited my perception of her. I was ashamed of her English. I believed that her English reflected the quality of what she had to say. That is, because she expressed them imperfectly, her thoughts were imperfect. And I had plenty of evidence to support me: the fact that people in department stores, at banks, and at restaurants did not take her seriously, did not give her good service, pretended not to understand her, or even acted as if they did not hear her.
I started writing fiction in 1985. And for reasons I won’t get into today, I began to write stories using all the Englishes I grew up with: the English she used with me, which for lack of a better term might be described as “broken”, and what I imagine to be her translation of her Chinese, her internal(内在的) language, and for that I sought to preserve the essence, but neither an English nor a Chinese structure: I wanted to catch what language ability tests can never show; her intention, her feelings, the rhythms of her speech and the nature of her thoughts.By saying “Language is the tool of my trade”, the author means that.
| A．she uses English in foreign trade |
| B．she is fascinated by languages |
| C．she works as a translator |
| D．she is a writer by profession |
The author used to think of her mother’s English as.
| A．impolite | B．amusing | C．imperfect | D．practical |
Which of the following is TRUE according to Paragraph 3?
| A．Americans do not understand broken English. |
| B．The author’s mother was not respected sometimes. |
| C．The author’s mother had positive influence on her. |
| D．Broken English always reflects imperfect thoughts. |
What is the passage mainly about?
| A．The changes of the author’s attitude to her mother’s English. |
| B．The limitation of the author’s perception of her mother. |
| C．The author’s misunderstanding of “limited” English. |
| D．The author’s experiences of using broken English. |
Do’s and Don’ts in Whale(鲸)Watching
The Department of Fisheries and Oceans has developed guidelines for whale watching in Johnstone Strait,where killer whales are found on a daily basis each summer. It is strongly recommended that vessel(船只)operators follow these guidelines for all kinds of whales.
●Approach whales from the side, not from the front or the back.
●Approach no closer than 100 metres, then stop the boat but keep the engine on.
●Keep noise levels down-no horns, whistles or racing of engines.
●Start your boat only after the whales are more than 100 metres from your vessel.
●Leave the area slowly, gradually moving faster when you are more than 300 metres from the whales.
●Approach and leave slowly, avoiding sudden changes in speed or direction.
●Avoid disturbing groups of resting whales.
●Keep at low speeds and remain in the same direction if travelling side by side with whales.
●When whales are travelling close to shore, avoid crowding them near the shore or coming between the whales and the shore.
●Limit the time spent with any group of whales to less than 30 minutes at a time when within 100 to 200 metres of whales.
●If there is more than one vessel at the same observation spot, be sure to avoid any boat position that would result in surrounding the whales.
